To (I1/ZZ wir/0m, it Tf1/'wy concern:

Be it known that I, EDUARD HERZIG, a citizen of theUnited States, and a residentof West.

Hoboken, county of Hudson, AState of New Jersey, have invented certain new and useful Improvements in Shuttles, of lowing is a specification.

My invention relates to shuttles such as are used in looms, and has for its object to increase the thread-carrying capacity of .shuttles of this description and to otherwise improve the construction of such shuttles, as

will appear from the detailed description following.

The features of novelty will be pointed out in the appended claims.

Referring to the drawings, which illustrate a specific embodiment of my invention, Figure l is a plan view of a loom-shuttle with my improvements applied thereto. Fig. 2 is an enlarged sectional View on the line 2 2 ofk Fig. 1, and Fig is an inverted plan view of a portion of the shuttle.

A is the shuttle-body, which may be of any approved shape and is provided with an opening A'. A plate B is secured to the shuttlebody in such a manner as to form a'bottom for said opening, as clearly shown in Fig. 2. An upright hollow support C forms part of or is secured to said plate B and is provided with a projection C' near its upper end. rlhe support C is adapted vto carry the spool D, on which is wound the thread E, said spool D being provided with a lslot D', which may be of the bayonet type and which cooperates with the projection C' on the support C to prevent the spool D from being accidentally pulled from the supportl C, it being understood that the spool D does not turn as the thread is used up, said spool being held against turning by the pin-and-slot connection with the support C. Inside of the support C is located a liningC2, which is made of wood or any similar substance and is forced into .the

support C, so as to be practically integraltherewith. `lnto this lining C2 is glued or otherwise secured a tube C3, which may be made of porcelain or any other Suitable subl stance which will alford a hard smooth guidesurface for thethread to prevent itfrom being torn or broken. An arm F, made in such a manner as to have a certainl amount of which the fol-` which its into an angular opening in the plate B. This structure prevents the pivot-screw 'F' from turning and becoming loose and prevents the arm F from wabbling. The said'arm F is arranged to swing on the pivot F' into the position shown b v dotted lines in-Fig. 1, the free end of said arm lF entering a notch F3 in the shuttle-body A, and in this position the arm serves as an additional means for preventing the thread-carryingspool from leaving the su pportC. When the pivot F' of the arm F is arranged'parallel with-the spool-support C, as shown, so that the saidarm swings 1n al plane parallel with the end face of saidspool, an endwise or axial movement of the spool will have no tendency to swing the said arm F on its pivot into the open position. A material advantage is` thus gained over struc' `tures in which vthe pivot of the locking-arm runs at substantially right angles to thespoolsupport. As 'the shuttle used in a loom the thread E will leave the spool, taking the direction indicated by the arrow a in Fig. -1, and d will pass down through the tube C3, along the under side of :the plate B, and up through an elongated eye G, made from porcelain or other material., From the eye G the thread passes through another porcelain eye H, which is mounted on a cross-bar H', secured to thel shuttle-'body A, to an eyelet'I, mounted or secured to an arm J, pivoted at J 'on the crossbar H' yAfter leaving the eyelet I the'thread passes over to and through an eyelet K', secured to or forming partof another arm K, which.is pivoted at K2, also on the. cross-bar H'., The thread then passes back to and through another eyelet J2 on the arm J and then back to and through another eyelet K3 on the arm K. Afterieaving the eyelet K3 the said thread is passed through another eyelet J 2 on the arm J and then back again to and through an; eyelet K2. on the armA K, after which the Jthread passes through an eyelet L,

mounted in a box portion M, -it being understood that gthe portion M vforms a container for the arms J and K and their respective eyelets, the said portion M being itself mounted .and secured on the shuttle-bodyA. From the eyelet L the thread passes through two eyelets N and N', secured to the shuttle A, and" then through an eyelet O, secured to the end of a' spring Oi, which has its other end fastened in an aperture in the shuttle A. After leaving the eyelet O the thread passes through an eyelet Pin -the shuttlebody A and then to lthe IOO IIO

point where the said-thread is being used.

The arms J and K are pressed away from each other to bring a tension on the thread by a spring Q, having two members Q/ and Q2, the said spring Q, being coiled around a projection R on an arm R', pivoted tothe plate B at R2, as shown in Fig. 3. The rivet forming the pivot R2 is so tight that the arm R' will be held stationary during the normal operation of the shuttle; but for adjusting purposes the said arm R' may be moved on its pivot R2 by means of a suitable tool to increase or lessen the tension of the spring Q on the arms J and K, a slot B' being provided in the plate B for this purpose. i

With the structure I have described it will be seen that the thread-carrying capacity ot the shuttle is materially increased and that the thread is subjected to a uniform tension through the medium of the spring-pressed arms J and K and the spring O', and thus prevented from sagging, the resulting work being therefore of a very uniform character. My improved shuttle is also very easily dismantled for any purpose whatsoever, and the spools otl thread are also very easily inserted, it being only necessary to mount the thread-carrying spool upon the support C and then thread the shuttle, whereupon it is ready for use.

Various modifications may be made without departing from the spirit oi' my invention.

I claim and desire to secure by Letters Patent- 1. A shuttle comprising a body provided with a recess or chamber, a support extending transversely of the shuttles path within said recess and secured at one end to a wall of the recess, the other end of the support being free to allow a spool to be slipped thereover, and an arm pivoted at one side of said recess, and mounted to swing across the same about an aXis parallel with the said support, so that an endwise or axial movement of the spool will have no tendency to swing the said arm on its pivot.

2. A shuttle provided with a tension device comprising pivoted arms having threadguides, springs engaging said arms, and means for moving Said springs toward or from the pivot portions of the arms.

8. A shuttle provided with a tension device comprising a pivoted arm having threadguides, mating thread-guides arranged opposite the first-named thread-guides, a spring engaging the pivoted arm, and means for moving said spring toward or from the pivot of the arm.

4. A shuttle provided with a movable tension device having thread-guides, a spring tor actuating said device and means for moving the spring in its entirety to vary its pressure on said movable device.

A shuttle comprising a body provided with a recess or chamber, a support extending transversely or' the shuttles path within said recess, a spool carried by said support, means for locking said spool to the support, a second chamber or recess arranged within the iirst-named chamber, a mo f'able tension device located in said secoml-named chamber and provided with threzul-guides, and a spring` for actuating said device.

6. A shuttle comprising a body provided with a recess or chamber, a support extending transversely ot' the shuttles path within said recess, a spool carried by said support, a movable arm adapted to lie near one end face of the spool` said arm being arranged to move in a plane parallel with the end tace of the spool, a second chamber or recess arrangedy within the iirst-named chamber, a tension device arranged within said second-uamed chamber and comprising pivoted arms having thread-guides, springs engaging said arms, and means for moving said springs toward or from the pivot portions ot the arms.

7. A shuttle having a stationary spool-support, a movable resilient arm adapted to lie near one end face of the spool, said arm being arranged to move in a plane parallel with the end face of the spool, and a shuttle-body having a notch into which the free end of said arm is adapted to spring when in its locking position.

8. A shuttle con'iprising a body provided with a recess or chamber, a support extending transversely of the shuttles path within said recess and secured at one end to a wall of the recess, the other end ot the support being free to allow a spool to be slipped thereover, and a resilient arm pivoted at one side of said recess and mounted to swing across the same, about an axis parallel with the said support so that the spool will lie between said arm and the wall to which the support is secured, the body of the shuttle having a notch into which the free end of said arm is adapted to spring when in its locking position.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
